[Nhcoll-l] Bio detergent in a bone collection

[Gali Beiner]

Dear All,

We received a (recent) bone collection of reptilia, part of which had been
prepared using bio powder detergent (active enzymes). Accumulations of the
powder are still present in some of the bones and apparently are still
active, causing damage to the bones. It will be very helpful to hear from
those of you who may have dealt with this problem and perhaps successfully
removed or neutralized the action of the bio agent.

Basically I'm considering two ways of action: trying to find a way to wash
out or chemically neutralize the active enzymes (somewhat tricky because
apparently more than one kind of commercial bio detergent product had been
used and the accumulations are pretty stubborn as far as rinsing is
involved), and/or planning a specialized storage environment for specimens
with such accumulations. Learning from you would be most helpful!

Thank you,

Gali
